Galvanized pipes are made by reacting the molten metal with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the in the hot dip bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized steel pipe substrate undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a compact structure. The alloy layer is integrated with the pure zinc layer and the steel tube substrate. Therefore, it has strong corrosion resistance.
Galvanized pipe production process, galvanized steel pipe production process, galvanized seamless pipe production process, galvanized seamless steel pipe production process.
Galvanized pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction, and is one of the twenty key products developed in my country. For liquid transportation: water supply, drainage, sewage treatment projects, mud transportation, marine water transportation. For gas transportation: gas, steam, liquefied petroleum gas. Structural use: for piling pipes, for bridges; for wharfs, roads, building structures, marine piling pipes, etc.
The difference between galvanized steel pipe and galvanized square pipe
In order for galvanized pipes to make our current construction industry more perfect and more pioneering, we should pay attention to their different characteristics when choosing square and rectangular pipes or round pipes, so as to make the best choose. When the galvanized pipe is in use, although the internal pressure and external pressure are relatively uniform, it does have certain limitations when used. If it is subjected to the condition of plane bending, the bending strength of the round tube is not as high as that of the armor tube. In particular, the skeletons of some agricultural machinery and steel-wood furniture use square and rectangular tubes. Of course, we'd better choose galvanized steel pipes according to different ways of use. If it is under the speaker of the market itself, the contribution of galvanized seamless steel pipe to the building materials market is still indelible, and there are already many businesses that may have some bargain hunters.
